Peach tree named ‘Supechnineteen’

ABSTRACT

A new and distinct peach tree variety,  Prunus persica,  cv. ‘Supechnineteen’ is characterized by fruit with large size.

Latin name of the genus and species claimed: Prunus persica.

Variety denomination: ‘Supechnineteen’.

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new and distinct variety of peach, Prunus persica cv. ‘Supechnineteen’. The new variety was first selected in May 2011 by Terry Bacon as breeder number: ‘PE1319W’. The new variety was first evaluated by Terry Bacon near Wasco, Calif. in Kern County. The NEW variety ‘Supechnineteen’ was originated by hybridization.

The new variety ‘Supechnineteen’ is characterized by its large size and early ripening.

The seed parent is ‘PE921W’ (unpatented Sun World peach), and the pollen parent is unknown, being from bulk pollen. The parent varieties were first crossed in February 2008, with the date of sowing being February 2009, and the date of first flowering being February 2011. The new peach variety ‘Supechnineteen’ was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in January 2011, by grafting.

The new variety ‘Supechnineteen’ is distinguished from its seed parent, ‘PE921W’, in that the new variety ripens about ten days later than ‘PE921W’. ‘Supechnineteen’ ripens starting about May 3^(rd) compared to April 23^(th) for ‘PE921W’. The new variety ‘Supechnineteen’ also has a larger fruit size at 77 mm fruit diameter compared to 65 mm fruit diameter for ‘PE921W’.

The new variety ‘Supechnineteen’ ripens at nearly the same time as ‘Snow Angel’ (U.S. Plant Pat. No. 18,750). However, the new variety ‘Supechnineteen’ has larger sized fruit, at about 77 mm compared to 64 mm for ‘Snow Angel’. The new variety ‘Supechnineteen’ has similar fruit size as ‘Spring Snow’ (U.S. Plant Pat. No. 9,883) but ripens 20 days earlier.

The new variety ‘Supechnineteen’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding and grafting.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic illustration shows typical specimens of the foliage and fruit of the present new peach variety ‘Supechnineteen’. The illustration shows the upper and lower surface of the leaves and exterior and sectional views of the fruit. The photographic illustration was taken shortly after the fruit was picked and the colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with a capital letter designate values based upon The R.H.S. Colour Chart published by The Royal Horticultural Society, London, England, 1986.

The descriptive matter which follows pertains to 3 year old ‘Supechnineteen’ trees on Nemared (unpatented) rootstock, grown in the vicinity of Wasco, Kern County, Calif., during 2014, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
